Illustration for the article: 5 Signs Your Boiler Needs Replacing

Most boilers last 10 to 15 years. As they age they become less efficient and less reliable. Here is what to look out for.

Your energy bills keep rising

An older boiler has to work harder to heat the same home. If your usage has not changed but your bills have, the boiler may be to blame.

Check the efficiency rating

Boilers made before 2005 are often rated G, compared with A for a modern condensing boiler.

It keeps breaking down

One repair is normal. Several in a year usually means the cost of repairs will soon outweigh a replacement.

Parts are hard to find

Manufacturers stop making parts for older models, which makes every repair slower and more expensive.

Strange noises or smells

Banging, whistling or a yellow flame all need checking by a Gas Safe engineer straight away.
